TCP model based on the Network Simulation Cradle by Sam Jansen. The NSC is available on the http://research.wand.net.nz/software/nsc.php page. You must read the inet/3dparty/README before use this TCP implementation. This model is compatible with both IPv4 (Ipv4) and IPv6 (Ipv6). The TCP_TRANSFER_OBJECT data transfer mode isn't implemented yet. See the ITcp for the TCP layer general informations.

Settings

stackName: You can select a TCP implementation with the stackName parameter (On the 64 bit systems, the liblinux2.6.26.so and liblinux2.6.16.so are available only).

stackBufferSize: The buffer size value for selected TCP implementation. The NSC sets the wmem_max, rmem_max, tcp_rmem, tcp_wmem parameters to this value on linux TCP implementations. For details, you can see the NSC documentation.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.
